Abstract: A method for driving a plasma display panel includes a first mode for carrying out display by applying sustain pulses whose number corresponds to brightness weight of subfields; a second mode for carrying out display in which the one field period includes a smaller number of subfields than that of the first mode and the number of sustain pulses in the one field period is set to be more than that in the first mode; and a third mode for carrying out display in which an address time of a non-lighting line of the second mode is shortened and the shortened time is set in a sustain period. The first mode or the second mode is shifted to the third mode when a lighting rate is a predetermined value or less and a gradation of image is a predetermined value or more of each subfield.

Abstract: A plasma display panel driving method and a plasma display device estimate the highest temperature and the lowest temperature the panel can have, according to the temperature detected by the thermal sensor, and appropriately drives the panel, to improve the image display quality. Provided are at least three driving modes having different sub-field structures: a low-temperature driving mode, an ordinary-temperature driving mode, and a high-temperature driving mode. To drive the panel, estimates of the highest temperature and the lowest temperature the panel can have are made from the temperature detected by the thermal sensor, the temperature condition of the panel is determined from the estimated highest temperature or lowest temperature, and the driving mode is switched appropriately for the panel temperature condition.

Abstract: The present invention provides a method of driving a plasma display panel that displays an image with high brightness, high contrast, and high display quality by stabilizing selective initializing operation. To realize it, a plurality of subfields each having a setup period, an address period, and a sustain period are provided in one field period. Retention time for retaining voltages to be applied to a scan electrode and a sustain electrode is provided between time when voltage for weakening the final sustain discharge in the sustain period is applied to the sustain electrode and time when a ramp waveform voltage which decreases is applied to the scan electrode in the setup period in the following subfield. The retention time is controlled based on average brightness of image signals or ambient temperature.
